Intake Manifold Gasket Set for 1965-1990 Big-Block Chevrolet Oval Port 396-454
Oval port and rectangular port big-block heads do not share a gasket, and fitting the wrong one either blocks part of the port or leaves the runner hanging over the edge, which costs flow and invites a vacuum leak. This is the oval port set in synthetic fiber composite, multi-piece so each side and end seal goes on independently.
Edelbrock 7203 Intake Gasket Set Specifications:
- Synthetic fiber composite construction, grey.
- Multi-piece configuration, six manifold bolt holes.
- For Mark IV big-block Chevrolet oval port heads, 396, 402 and 454 cubic inch.
- Applications span 1968-1989 Chevrolet and GMC applications.
- Valley pan is not included. Confirm oval versus rectangular port before ordering.
